Abstract: An atomic layer deposition method for manufacturing a platinum-based alloy catalyst includes applying a support in a reactor and depositing an alloy of platinum and a non-platinum metal on the support through a super cycle comprising a first sub-cycle and a second sub-cycle.

Abstract: Electronic device includes first wireless communication interface; second wireless communication interface; and controller.

Abstract: A pouch-type battery case includes a cup portion, which accommodates therein an electrode assembly formed by stacking an electrode and a separator, and a plurality of die edges connecting an outer wall of the cup portion to a side extending from the outer wall. The die edges include a first region, which is rounded at a first radius (r1) of curvature and at which an electrode tab extending from the electrode is positioned, and a second region which is other than the first region and rounded at one or more second radii (r2, r3, r4) of curvature less than or equal to the first radius (r1) of curvature. The second region is divided into an inner region and an outer region with respect to the first region, and the radius (r2) of curvature in the inner region differs from the radii (r3, r4) of curvature in the outer region.

Abstract: A method for synthesizing a pre-hydrolyzed polysilicate, wherein a polysilicate is applied as a reactant when synthesizing the pre-hydrolyzed polysilicate, and the total amount of water added in the reaction system is specified. The method is capable of omitting a condensation reaction by applying a polysilicate as a reactant, thereby significantly shortening synthesis time and reducing production costs when compared with a typical synthesis method in which alkoxysilane-based monomer compound is used as a reactant. In addition, the gelation reaction time and the weight average molecular weight can be easily controlled, and a pre-hydrolyzed polysilicate excellent in storage stability and processability can be synthesized.

Abstract: A portable device includes a keyboard unit; a display unit; a connection unit which is connected to each of the keyboard unit and the display unit, moves relatively with respect to each of the keyboard unit and the display unit, and supports the display unit so that the display unit covers or uncovers the keyboard unit; and a controller which is placed inside the connection unit and controls operation of the portable device.

Abstract: An electronic apparatus includes a body and a display panel installed at a front side of the body to display an image. The body includes a first member to form a portion of the body and allowing the display panel to be installed thereon, and a second member to form a remaining portion of the body and rotatably installed at the first member. As the second member serves as a support, the electronic apparatus may be disposed in a second mode for a user to conveniently use the electronic apparatus.
